On the Landis Conjecture for Positive Quasi-linear Operators on Graphs
Ujjal Das, Matthias Keller, Yehuda Pinchover
We prove a Landis type unique continuation result for positive quasi-linear operators on graphs. Specifically, we give decay criteria that ensures when a harmonic function for a po…

On Landis' conjecture for positive Schrödinger operators on graphs
Ujjal Das, Matthias Keller, Yehuda Pinchover
In this note we study the Landis conjecture for positive Schrödin\-ger operators on graphs. More precisely, we prove a Landis-type result in the form of a decay criterion that ens…
